Abstract
Apple is one of most important and commonly cultivated fruits. Today in Republic of Serbia there is a large number of modern apple plantations. After harvest apple fruits are stored in cold storages for a long period of time. During the storage period various rot agents can infect apple fruits, and in most cases the rot is caused by phytopathogenic fungi. Storing apple method in cold storages with controlled atmosphere and ultra low oxygen (ULO) reduces the percentage of rot, but it also changes the structure of pathogen population. In Serbia, treatments against apple fruit rot are conducted 3 to 14 days prior to harvest, and there are no registered chemical preparations for fruit treatment in postaharvest period. In this paper, population structure of apple fruit rot causal agents in ULO storages at different locations (Tavankut, Jazak, Mala Remeta, Titel and Kukujevci) was investigated. After sample examination from ULO storages at five locations, the following genera of phytopathogenic fungi were detected: Penicillium, Botrytis, Alternaria Fusarium, Neofabrea, Mucor, Monilinia. The most commonly isolated species belong to the genera Penicillium and Neofabrea.
